Judging by these pictures, people will do some pretty crazy things to get into the Guinness book of World Records...
World's longest fingernails
Chris 'The Duchess' Walton has fingernails that measure more than three metres long. She's been growing them for 18 years. No wonder it's so difficult to text!
World's largest afro
This is Aevin Dugas from New Orleans in America, and she's the proud owner of the most enormous natural afro hair with a circumference of 1.32 metres. That definitely beats Beyonce's 'fro in her Work It Out music video.
World's biggest chocolate bar

World's biggest chocolate bar
These two little girls look VERY excited about it. The question is- did they get to eat it once the cameras and journalists had all gone home?
A fire truck converted into a wedding chapel
This bizarre vehicle made the record books because it's been converted into a wedding chapel. The Rev. Darrell Best from Illinois, USA, created the chapel which can get up to speeds of 60 miles per hour.
World's longest crocodile?
You definitely wouldn't want to come across this 6.4 metre-long beast if you were out swimming here in the Philippines... The record for the world's biggest croc is a very closely fought one, so the experts are waiting for more evidence before deciding whether this is it.
Dr Who superfan from Doncaster, Rob Hull, has set a world record after collecting 571 unique Dalek models.
